Что мне не хватает в этом блоке ant trycatch?

Я пытаюсь создать блок trycatch в своем сценарии ant. Я получаю эту ошибку:

* ОБНОВЛЕНИЕ *

org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-antrun-plugin:1.7:run (test-compile) on project PROJECT: An Ant BuildException has occured: Problem: failed to create task or type trycatch

Я пытался следовать примерам try catch, но ни один из них не сработал. http://ant-contrib.sourceforge.net/tasks/tasks/trycatch.html

Я получаю эту ошибку, одно и то же имя не определено во всех случаях. Я не знаю, правильно ли я вставляю этот блок, потому что я пытаюсь поместить его на определенные этапы сборки.

Как я могу заставить этот trycatch работать?

* ОБНОВЛЕНИЕ *

Я все еще получаю те же ошибки
